A computer virus dubbed the world's "first cyber superweapon" by experts and which may have been designed to attack Iran's nuclear facilities has found a new target -- China.
The Stuxnet computer worm has wreaked havoc in China,
infecting millions of computers around the country, state media reported this
week.
Stuxnet is feared by experts around the globe as it can
break into computers that control machinery at the heart of industry, allowing
an attacker to assume control of critical systems like pumps, motors, alarms
and valves.
It could, technically, make factory boilers explode,
destroy gas pipelines or even cause a nuclear plant to malfunction.
The virus targets control systems made by German
industrial giant Siemens commonly used to manage water supplies, oil rigs,
power plants and other industrial facilities.
"This malware is specially designed to sabotage
plants and damage industrial systems, instead of stealing personal data,"
an engineer surnamed Wang at antivirus service provider Rising International
Software told the Global Times.
"Once Stuxnet successfully penetrates factory
computers in China, those industries may collapse, which would damage China's
national security," he added.
Another unnamed expert at Rising International said the
attacks had so far infected more than six million individual accounts and
nearly 1,000 corporate accounts around the country, the official Xinhua news
agency reported.
The Stuxnet computer worm -- a piece of malicious
software (malware) which copies itself and sends itself on to other computers
in a network -- was first publicly identified in June.
It was found lurking on Siemens systems in India,
Indonesia, Pakistan and elsewhere, but the heaviest infiltration appears to be
in Iran, according to software security researchers.
A Beijing-based spokesman for Siemens declined to comment
when contacted by AFP on Thursday.
Yu Xiaoqiu, an analyst with the China Information
Technology Security Evaluation Centre, downplayed the malware threat.
"So far we don't see any severe damage done by the
virus," Yu was quoted by the Global Times as saying.
"New viruses are common nowadays. Both personal
Internet surfers and Chinese pillar companies don't need to worry about it at
all. They should be alert but not too afraid of it."
A top US cybersecurity official said last week that the
country was analysing the computer worm but did not know who was behind it or
its purpose.
"One of our hardest jobs is attribution and
intent," Sean McGurk, director of the National Cybersecurity and
Communications Integration Center (NCCIC), told reporters in Washington.
"It's very difficult to say 'This is what it was
targeted to do,'" he said of Stuxnet, which some computer security experts
have said may be intended to sabotage a nuclear facility in Iran.
A cyber superweapon is a term used by experts to describe
a piece of malware designed specifically to hit computer networks that run
industrial plants.
"The Stuxnet worm is a wake-up call to governments
around the world," Derek Reveron, a cyber expert at the US Naval War
School, was quoted as saying Thursday by the South China Morning Post.
"It is the first known worm to target industrial
control systems."
